Here is the tentative schedule of lectures and due dates. The lecture material for future lectures may change.

About deadlines: Assignments are generally due according to this schedule:

  • Projects are generally due on Fridays at 8pm
  • Labs are generally due on Tuesdays at 8pm
  • ❓ Post-Lecture Quizzes (PLQs) are due the day before the next lecture at 11:59pm

Code from the lectures is available at github.com/csci1670/cs1670-lectures. See the notes for each lecture for more info.

Seminar entries on Fridays are CS 1690 seminars, which are mandatory for students in CS 1690/2670 to attend.
This view hides the Friday CS 1690 seminars, which students in CS 1670 only do not attend. If you are enrolled in CS 1690 or CS 2670, switch to the OS with lab view above.
